Use IPU2 CSI1 for adv7180 camera fail

wilsonchen — Thu, 19 Jan 2017 03:26:42 GMT

hi,

I want to use the ipu2 csi1 for adv7180 camera,but i fail.

I have use the tips :

iMX6DQ ISL79985/79987 MIPI CSI2 CVBS camera surround view solution for Linux BSP

and the boundarydevice's kernel.

the adv7180 driver is ok,but when i open the camera app,it send:

ERROR: v4l2 capture: mxc_v4l2_prepare_bufs buffers not allocated,index=0, length=622080
ERROR: v4l2 capture: mxc_streamon buffer has not been queued yet

the OS is the android4.4.2 android android5.1.1, the errors is the same.

what's the problem?

Hi wilson

for adv7180 mxc_v4l2_tvin.out should be used, also seems

this configuration is used on BD board imx6q-nitrogen6x.dts
https://github.com/boundarydevices/linux-imx6/blob/boundary-imx_4.1.15_1.0.0_ga/arch/arm/boot/dts/imx6q-nitrogen6x.dts

Best regards
igor
